The Battle of Othée was fought between the citizens of Liège and a professional army under command of John the Fearless on 23 September 1408.

[2] Henri of Horne was aware that his troops were no match for the professional army heading his way, and therefore proposed to leave the city and start a guerilla war from the countryside.

To face them Duke John decided upon a tactical plan that mimicked the winning English system during the Hundred Years' War.

[3] Despite the bravery of the rebels attack they were repulsed by the ferocious Burgundian archery and then surrounded by the Duke's reserve cavalry and cut to pieces.

The ensuing executions of leading insurgents and their families, including the widow of Henry of Horne, led to John of Bavaria's nickname "the Pitiless."
